Event system is not behaving like its documentation

There is multiple discrepancies between event documentation and the reality (test on XS 7.1 fully up-to-date)

FYI, documentation is here: http://xapi-project.github.io/xen-api/classes/event.html

• obj_uuid field does not exist
• snapshot field is not documented
• timestamp is always 0.0
• different ID formats between event.inject (00000000000009163547,00000000000000000000) and events (9163548)
• event.inject does not guarantee that an event with the returned ID will be emitted

This is a real problem when we want to rely on some features that are not behaving like expected/documented. Is there a more up-to-date documentation? Are we missing something?
